Description

Installation apparatus for split type air conditioner
Technical Field
The present invention relates to an air conditioner. In particular, the present invention relates to an apparatus for installing a split type air conditioner.
Background
Air conditioning is a joint expression of air conditioning into a desired state. It can heat air during cold periods, cool air during warmer periods, or can be used to purify air when the air contains undesirable particles. However, the expression air conditioning is most often used when emphasis is given to cooling. As a product, air conditioners may look in various forms and be used in various ways, but they all share the same basic technology. An air conditioner includes a compressor, a condenser, an evaporator, and typically also an expansion device.
There are different types of air conditioners. One type of air conditioner may be referred to as a split-type air conditioner. In a split-type air conditioner, the condenser and evaporator are located in two distinct separate units that are interconnected via piping to circulate refrigerant from one unit to the other.
Another type of air conditioner may be referred to as a Packaged air conditioner. An integral Air Conditioner (AC) can be said to be a self-contained system in which all cooling cycle components, such as the compressor, condenser, expansion device, evaporator and control system, are enclosed in a single package. Among the most common residential applications in an integral system are window AC, integral terminal AC (ptac), and also portable AC units.
Unitary air conditioners have the advantages of easy installation, relatively small footprint, flexibility in heating/cooling the various rooms, and low cost.
In contrast, a split-type air conditioner includes at least two factory-manufactured separate components that are designed to be used together. In a split system, the outdoor unit is separated from the indoor unit(s) by a distance by semi-rigid pipes containing a refrigerant (at high pressure) that creates a cooling/heating effect in the system. Among other advantages, the split system can provide a higher efficiency ratio at various capacities and operating conditions. Additionally, in a split AC system, the compressor, outdoor heat exchanger, and outdoor fan may be located further away from the interior space than just on the other side of the same unit (as in a PTAC or window air conditioner), thereby achieving lower indoor noise levels.
When installing an air conditioner having an outdoor unit, such as a split type air conditioner or a similar type of air conditioner, installation is often difficult. Improvements in air conditioners are always desirable. Accordingly, there is a need for an improved air conditioner, and in particular an improved mechanism for mounting an air conditioner.
Disclosure of Invention
It is an object of the present invention to provide an improved air conditioner, and in particular an improved apparatus for mounting an air conditioner.
This object is achieved by an apparatus as set forth in the appended claims.
In accordance with the present invention, a mounting apparatus is provided that is configured to hold a window mounted split air conditioner. The mounting apparatus includes a support structure configured to be mounted on the window sill. Thus, the installation apparatus for easy installation can make the outdoor unit of the split type air conditioner easy to install, and does not need to be screwed to the outdoor wall.
According to one embodiment, the mounting apparatus includes a mounting mechanism attached to the support structure and configured to be attached to an outdoor unit of the split air conditioner. The mounting mechanism may be configured to move the outdoor unit between a first position at the window to a second position outside the window in use. Thereby, since the outdoor unit can be easily installed from the inside via the window, it can be facilitated to place the outdoor unit in an operation position.
According to one embodiment, the mounting mechanism comprises a set of hinge elements designed to hold the outdoor unit. Thereby, the mounting mechanism may be implemented in a manner that is easy to use and may be easily attached to the outdoor unit.
According to one embodiment, the support structure comprises a clamping element for fixing the support structure to the window sill. Thus, the support structure can be easily installed and removed without leaving any permanent marks on the wall on which the air conditioner is installed.
According to one embodiment, the support structure includes channels for at least one connection between the indoor unit and the outdoor unit of the split type air conditioner. Thus, the window can be maintained in the closed position, and it is not necessary to open a hole in the wall for connecting the indoor unit to the outdoor unit of the split type air conditioner.
According to one embodiment, the support structure comprises a support element for carrying the weight of the indoor unit inside the space to be conditioned. Thus, the support unit can be used to carry both the outdoor unit and the indoor unit, and there is no need to provide a support structure that is specified only for the indoor unit.
According to one embodiment, the support structure comprises a telescopic profile which is adjustable to the width of the window opening. Hereby an easy to use fastening mechanism for fixing the support structure to the window sill is achieved. Furthermore, the support structure can be easily adapted to different window sizes.

Detailed Description
The present invention now will be described more fully hereinafter with reference to the accompanying drawings, in which certain embodiments of the invention are shown. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided by way of example so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art. For example, the same or similar components of different embodiments may be interchanged between different embodiments. For example, an air conditioner may be described herein as a cooling system, but if the system is operating in a heating mode, the cooler may likewise be a heater. Some components may be omitted in different embodiments. Like reference numerals refer to like elements throughout the specification.
As the inventors have recognized, split-type air conditioners are difficult and often expensive to install. Therefore, it would be advantageous to improve the mounting apparatus of the air conditioner. Advantageously, the air conditioner may also include self-installing equipment to facilitate its installation, thereby eliminating the need for high skill or certified human labor.
A description is given below of the split type air conditioner. The various parts of the description with reference to fig. 1 to 5 are given to provide a context to better understand the benefits of the mounting device according to the invention.
Fig. 1 shows a schematic diagram of an embodiment of an air conditioner 100. Air conditioner 100 may be said to be split and includes an indoor unit 101 and an integral outdoor cooling unit 102. The units 101, 102 are interconnected via an intermediate connection system 103. Further, a mounting apparatus 104 for mounting the air conditioner 100 is depicted. Also depicted is a window 105 with the air conditioner 100 installed. In this exemplary embodiment, window 105 is a standard suspended window. The air conditioner may also be mounted on other types of windows, such as a sliding window or some other openable window. To enable compact installation of the outdoor unit 102, the outdoor unit may be provided with a fan arrangement that moves air from the top/bottom of the outdoor unit and out through the front air outlet. This makes it possible to install the outdoor unit at a position closer to the outer wall where the outdoor unit is located. Other advantages may also be realized, as set forth herein.
In fig. 2, an air conditioner 100 is depicted having an outdoor unit that includes an integral refrigeration system. However, it will be understood that outdoor units without an integrated refrigeration system may also use the principles of operation and other features of the fan configuration, as set forth herein. For example, a conventional split type air conditioner may be provided with an outdoor unit using the technology described herein. Thus, it will be understood that the embodiment of fig. 2 is illustrative of installation for illustrative purposes.
In fig. 2, an exemplary embodiment of the split type air conditioner 100 of fig. 1 is shown in more detail. Fig. 2 shows an indoor unit 101 and an outdoor unit 102. The indoor unit includes an air-liquid heat exchanger 203. The air-liquid heat exchanger 203 cools (or heats) air flowing in the indoor unit 101. Further, a liquid-refrigerant heat exchanger, specifically a compact liquid-refrigerant heat exchanger 204, is provided in the outdoor unit 102. The compact liquid-to-refrigerant heat exchanger 204 functions as an evaporator. Further, a main pump 205 is provided to circulate the liquid solution used as the energy transmission medium from the indoor unit 101 to the outdoor unit 102 (and back again). This will provide indirect cooling for cooling the indoor unit. The main pump may also be located in the outdoor unit 102. The liquid solution is circulated via the connection system 103. In this example, the connection system 103 is formed by two connection lines 206 and 207. Since the connection system 103 can be made to operate at a relatively low pressure (about 1 bar), the lines 206 and 207 may alternatively be hoses or similar devices that are easy to handle and may be provided with connectors that can withstand low pressures. The outdoor unit 102 further includes a refrigeration system including a compressor 216 that drives refrigerant back to the compressor 216 via an air-cooled heat exchanger 215, via an expansion valve 220, and the compact liquid-refrigerant heat exchanger 204. The refrigeration system of the outdoor unit can be installed in the factory so that the user or installer does not have to work on the circuit circulating the refrigerant. Then, the factory may be filled with the refrigerant circulating through the air-cooled heat exchanger 215. Then, since the refrigerant circuit of the outdoor unit 102 is sealed in the factory, there will be no need to handle the refrigerant during installation.
Further, the liquid tank 208 may be located at the top of the system. The liquid tank 208 may be connected to a circuit that circulates the energy-conveying medium. According to one example, the liquid tank may be connected to the suction port of the main pump 205. The tank 208 may include a level sensor 209 for controlling the amount of liquid solution circulating between the indoor unit 101 and the outdoor unit 102 required for normal operation of the system 100. A box 210 may be provided below the indoor heat exchanger 203 for collecting any condensate generated on the indoor heat exchanger 203. A sensor 211 may be provided to detect the water level inside the condensation box 210. The sensor 211 may generate a signal that may be used to control the condensate pump 212. When activated, the water pump 212 is adapted to pump water from the cartridge 210 to the outside of the indoor unit 101. In particular, water may be sucked to the outside of a building in which the indoor unit is installed to be released to the outside. Thereby, a device that can suck condensed water from the indoor unit 101 to the outside is realized.
According to some embodiments, water is pumped to the external unit 102. The pumped water may then be pumped, for example, through a drain line 213 to a spray device 214 located on top of an outdoor air cooled heat exchanger 215 connected to a compressor 216. Fig. 2 further depicts a fan 221 provided in the indoor unit 101 for circulating air in the indoor unit. Also, a fan 222 for circulating air in the outdoor unit 102 is provided in the outdoor unit. The connection system 103 may further be provided with a connection device 218. For example, the connection device 218 may be a quick connection for interconnecting the pipes of the indoor unit 101 with the pipes of the outdoor unit 102 in a quick and safe manner. The connection device 218 may advantageously be located on the top portion of the outdoor unit for easy access. By connecting the indoor unit 101 with the outdoor unit 102, the energy transfer medium can be circulated between the indoor unit 101 and the outdoor unit 102. Also, the condensed water may be transported from the indoor unit to the outdoor unit 102 via the connection system 103.
In use, the air conditioner 100 uses the external integral AC unit of the outdoor unit 102 to reduce the temperature of the energy transfer medium. A cooling effect is generated in the compact heat exchanger 204 located in the refrigeration system of the outdoor unit 102, thereby allowing the temperature of the energy transfer medium to drop, which is then transferred into the indoor unit 101 via the connection system 103. The energy transport medium at the lower temperature then absorbs thermal energy from the space to be conditioned by using the low pressure air-to-liquid heat exchanger 203 of the indoor unit 101. Then, when the energy transmission medium is heated in the indoor unit 101 installed in the indoor space to be conditioned, heat is returned from the internal unit 101 to the external unit 102 by returning the energy transmission medium to the external unit. Because the cooling capacity is generated isolated from the refrigeration circuit located in the outdoor unit 102, all heavy and noisy components can be confined to the external unit and the indoor environment can be nearly noiseless. Also, the space required for the indoor unit is very small. Because the connection system 103 for transferring heat between the indoor unit 101 systems may be a low pressure system, it may use an energy transfer medium that is easy to handle (such as water, water-based solutions) or some other liquid medium (such as ethanol).
Thus, according to some embodiments, an aqueous medium may be used to transport energy from the indoor space to be conditioned to the compact evaporator located in the external integrated unit. The main pump 205 will ensure the flow of the energy transfer medium by pumping the aqueous medium and the external cooling unit will reject the heat generated in the process to the surrounding outdoor air.
This is achieved because the external integrated cooling system located in the outdoor unit may include all of the standard constituent elements in a refrigeration system, such as a compressor, a condenser, an expansion device, an evaporator and control system, and a refrigerant.
In fig. 3, an exemplary outdoor unit 102 of a type similar to the embodiment of fig. 2 is shown. Fig. 3 shows a cross-sectional view from the side to the right and a cross-sectional top view to the right. In fig. 3, a compressor 216 is provided. In this exemplary embodiment, the compressor drives refrigerant back to the compressor 216 via the air-cooled heat exchanger 215, via the expansion valve 220, and the compact refrigerant-to-liquid heat exchanger 204. Further, a fan 230 is provided. In an embodiment, fan 230 is implemented by two axial fans. The outdoor unit 102 may be connected to the indoor unit via a connector 240. An electronic control box 250 may be provided to implement the control mechanism of the outdoor unit 102. Also, a free space 260 for air circulation is indicated in fig. 3. The fan 230 is arranged to move air in the outdoor unit so that the air does not have to pass through the rear surface of the outdoor unit when the outdoor unit is installed at a position close to a wall. Thus, since no air must pass through the back of the outdoor unit 102, the outdoor unit can be mounted very close to the wall or even mounted directly on the wall. This can make installation easier and the space required to install the outdoor unit is also smaller. An additional advantage may be that the load on the means for fixing the outdoor unit may be reduced.
As seen in the left side view in fig. 3, the compressor 216 may be located on the back of the outdoor unit 102, i.e., the side facing the wall when the outdoor unit is mounted thereon. The compressor 216 may also be centrally located in the lateral direction. Therefore, according to one embodiment, when the outdoor unit is mounted on a wall, the compressor is located at the center of the rear surface of the outdoor unit.
Further, according to some embodiments, the compact refrigerant-liquid heat exchanger 204 may be located on the back of the outdoor unit. Also, the electronic control box 250 may be located on the back side. This makes it possible to position the air-refrigerant heat exchanger 215 and the fan 230 in the remaining space of the outdoor unit to allow air to pass through the air-refrigerant heat exchanger 215. Air may be blown from the top section and/or the bottom section of the outdoor unit 102 through the air-refrigerant heat exchanger 215 by the fan 230. The air-refrigerant heat exchanger 215 can thus be placed in the inner part of the casing (just in front of the rest of the components), the separation between them forming a free passage in which the air can pass through the air-refrigerant heat exchanger 215 with a low restriction to flow. According to some embodiments, the fan 230 driving the airflow may be placed on top of the outdoor unit 102.
Since the compressor 216 is typically the heaviest component in the system, centering it on the back of the structure ensures a balance of the system with respect to the width of the unit. In a conventional air conditioner, it is often the case that: the heavier side of the outdoor unit corresponds to the side on which the compressor is located. This makes it difficult to transport and install the conventional outdoor unit.
Furthermore, positioning many of the heavier components as exemplified above at the back of the outdoor unit will provide the outdoor unit 102 with a center of gravity that is located below the center of the back of the outdoor unit 102. This will provide a balanced and stable structure for the outdoor unit 102.
Fig. 4a shows the layout of a standard outdoor unit. Fig. 4b shows the layout of the outdoor unit according to the above. In fig. 4a, a standard outdoor split AC unit 400 is shown. Fig. 4a further illustrates the structure 402 required to support the outdoor unit 400. Structure 402 is mounted on wall 300. The outdoor unit 400 has a rear surface air inlet 404 facing the wall surface. The outdoor unit 400 further has a discharge port 406 at the front of the outdoor unit 400. In fig. 4b, the outdoor unit 102 is shown with a fan arrangement according to the above. In fig. 4b, a structure 270 supporting the outdoor unit 102 is provided. Structure 270 is mounted on wall 300. The outdoor unit 102 has a topside air inlet 275. The outdoor unit 102 further has an air inlet of an air outlet 277 located at the front of the outdoor unit 102.
In the configuration depicted in fig. 4a, a minimum distance between the wall and the air inlet area of the outdoor unit 400 is required to ensure its proper operation. A typical minimum distance to the wall 300 is between 15cm and 30 cm. On the other hand, the layout of the outdoor unit 102 described herein does not require any separation between the outdoor unit 102 and the wall 300. As a result, the weight (W) supported by the structure 2702) And the resulting momentum (M)2) And the aim of having to deal with higher weight (W)1) And higher momentum (M)1) Structure 4 of the conventional outdoor unit 400The corresponding value of 02 is much smaller by comparison.
The air flow path may be configured according to a number of different alternatives. In fig. 5a to 5d, different embodiments are depicted which can be used in different configurations.
According to the embodiment of fig. 5a, a design is shown where the fan pushes air and the fan is located in the top section of the outdoor unit 102. In this configuration as shown in fig. 5a, the air inlet 291 is located at the top of the outdoor unit 102 and the air is pushed through the heat exchanger 215 until the air exits the outdoor unit from the outlet 293 at the front of the outdoor unit 102. The fan 230 may also be driven in a reverse direction. The fan 230 will then draw air in via the heat exchanger 215 to blow out at the top section of the outdoor unit 102. This configuration is shown in fig. 5 b.
In some embodiments, air may enter/exit the outdoor unit 102 via a bottom section of the outdoor unit. In fig. 5c, the design of placing the components inside the outdoor unit on the base 280 formed by the grill allows air to enter from below the outdoor unit. The fan 230 is then located at the bottom section of the outdoor unit 102 to push air out of the inlet 292 of the bottom section through the outlet 293 at the front of the outdoor unit 102 via the heat exchanger 215. The fan at the bottom of the outdoor unit 102 shown in fig. 5c may also be run in the opposite direction to draw air from the front section of the outdoor unit 102 through the bottom of the outdoor unit 102 via the heat exchanger 215. This configuration is shown in fig. 5 d. The top section may be closed when the bottom section of the outdoor unit is open.
According to some embodiments, two fans 230 may be used to provide airflow in the outdoor unit 102. By using two fans, the required airflow during heat rejection can be ensured while distributing more uniform air over the entire heat transfer area of the condenser(s), thereby allowing the use of smaller condensers as the heat transfer process is improved. According to one embodiment, when the outdoor unit is mounted on a wall, two fans are mounted on the top of the outdoor unit. In an alternative embodiment, when the outdoor unit is mounted on a wall, two fans are mounted on the bottom of the outdoor unit. In yet another alternative embodiment, the fans 230 are located at both the top and bottom, and air enters/exits the outdoor unit 102 at the top and bottom sections. In other words, air may be drawn through the heat exchanger 215 to exit at both the top and bottom sections or to be pushed in opposite directions. In such an embodiment, the fan 230 may be disposed at both the top section and the bottom section of the outdoor unit.
To further improve and facilitate the installation of the air conditioner in the window, an improved installation device may be provided. Accordingly, the mounting apparatus is designed to assist in mounting an air conditioner, such as the above-described indirect cooling type air conditioner, through the window. However, although an air conditioner system having indirect cooling is used in this specification, the mounting apparatus is not limited to such an indirect cooling system, but any air conditioner system having an external unit may be considered. Particularly any type of split-type air conditioner. In fig. 1, a mounting apparatus 104 having a support structure configured to be mounted on a window sill is shown. This may make installation easier. Also, the mounting apparatus may enable a single support structure to hold both the outdoor unit and the indoor unit as shown in fig. 1. This may be achieved by providing holding devices for both the indoor unit and the outdoor unit on the support structure. Specifically, a seating mechanism may be provided to hold the outdoor unit, and a support member may be provided to hold the indoor unit.
The indirect cooling system may include an external integrated outdoor cooling device, an indoor fan coil unit, and a hydraulic system for conveying an energy transfer medium between the two devices.
According to one embodiment, the mounting device 104 comprises a support structure with a clamping element, which can be easily fastened above (inside and/or outside) a wall surface or a window frame surface. The support structure may be used with a placement mechanism that is fixed to the support mechanism. The placement mechanism may be for moving the outdoor unit between a first position at the window and a second position outside the window. This may facilitate placing the outdoor unit in a suitable location. The placement mechanism may include a set of hinged elements designed to hold an outdoor unit, such as an integral cooling outdoor unit, and facilitate its displacement through the window to ultimately be placed outside the space to be conditioned by the installed air conditioner.
The hinge element may be equipped with a number of auxiliary components such as springs, gas dampers, hydraulic dampers, gears, pulley systems or any other component to balance and offset the weight of the unit during installation, so that the installer does not have to carry the unit through the window in which the air conditioner is to be installed.
The mounting apparatus may be configured to allow installation of the power lines, control connections, condensate drain lines, piping of the hydraulic system, and the air system through the window. This may be achieved by providing channels in the support structure for different connections between the indoor unit and the outdoor unit of the air conditioner.
Further, the mounting apparatus may be provided with a support member such as a hook or a hanger, which is located above the structure to support the weight of the indoor unit inside the space to be conditioned. Thus, the profile of the mounting device may preferably be such that it allows for a complete or almost complete closing of the window.
The support structure may be formed in a number of different ways. For example, in a first exemplary embodiment, the support structure may comprise a telescopic profile that is adjustable to the width of the window opening. The support structure sits on the window sill, where it can be fastened by elongating the telescopic profile in the transverse direction of the window opening. Additional safety elements may be attached to the support structure to provide additional support at the interior portion of the window frame. Attached to the top side of the support structure with the telescopic profile, the hinging system can be attached to provide a translational and/or rotational movement when performing the mounting of the outdoor unit. The articulated system then provides a seating mechanism.
In fig. 6, an exemplary embodiment of a mounting device for a window-mounted split air conditioner is shown, wherein the support structure has telescopic profiles forming the clamping elements. Fig. 6 shows a top view, a side view and a side view of the mounting device. In fig. 6, a wall 300 with a window is shown. The window has a window jamb 602 and a sill 603. The telescopic profile is formed by at least a first part 604 and a second part 605. Further, a lock 606 is provided for locking the telescopic profile in the extended position. Furthermore, in fig. 6 a safety element 607 is shown extending from the telescopic profiles 604, 605. One advantage of using telescopic profiles is that they can be installed in suspended windows, awning windows and also hinged windows, since the profile of the structure can be hidden in the frame structure.
In fig. 7, a second embodiment of the support structure is shown. Fig. 7 shows a top view, a side view and a different side view of the mounting device. In the embodiment according to fig. 7, it consists of a seating mechanism sitting on the window sill. The seating mechanism includes a plurality of brackets (e.g., two brackets) that may be attached to the wall surface of the window and the window sill to provide a clamping element. In particular, the seating mechanism may be attached without the need for screws, nails, or any other structural fixing method for fixing the seating mechanism to the window sill.
Each bracket includes two arms that grip the wall surface of the window to secure the support mechanism to the window sill. In fig. 7, the wall 300 has window sill 752. Each bracket has an outer arm 753 and an inner arm 754. Further, a safety lock 755 may be provided to lock the arms 753, 754.

Further, in side view C) of fig. 7, the seating mechanism is clamped using a lever mechanism 761.
In use, the seating mechanism can bear the weight of the outdoor unit by distributing the weight components of the unit into different resultant forces normal to the wall surface. Preferably, the seating mechanism is designed to distribute the force evenly across the wall 300. Further, the seating mechanism may have a rubber material facing the wall surface. Thus, the entire system can be made static by the action of frictional forces between the wall surface and the structural material of the seating mechanism. This design may provide a static system that balances the weight of the unit with the clamping mechanism. According to one embodiment, the seating mechanism may include a telescopic and adjustable structure on one side that is assembled to fit the wall/frame thickness.
In addition to the support structure that can be attached to the window frame, a mechanism for easily installing the outdoor unit may be provided. Different mechanisms for placing the outdoor unit in place outside the wall 300 may be used. Such as folding structures, rail structures, hand-manipulated straps, articulated arms, lift platforms, and the like. These mechanisms will be described in more detail below. Regardless of the placement mechanism used, it may be convenient to place the outdoor unit in place by allowing the user to use the placement mechanism to move the outdoor unit from the window to its final operating position. Thus, the user does not have to hold the outdoor unit by hand when bringing the outdoor unit to its final operating position. Instead, the placement mechanism may provide a predetermined path that the outdoor unit may follow. The user then only needs to attach the outdoor unit to the placement mechanism, preferably at the window. The outdoor unit may then be pushed into a position held by the placement mechanism.
In fig. 8, an exemplary folding mechanism is depicted. In fig. 8, some support structure (here denoted as 802) such as that described above is provided on the wall 300. Further, a folding hinge 803 is provided on the support structure. The hinge mechanism 803 may have a pivot 804 configured to rotate the holder to unload the outdoor unit 805 to its outer final position. Thus, by rotating the outdoor unit downward at the pivot, the outdoor unit 905 moves from the first position at the window to the second position where the outdoor unit is installed.
In fig. 9, an exemplary rail-type mechanism is depicted. In fig. 9, some support structure (here denoted 902) such as that described above is provided on the wall 300. In fig. 9, a rail type mechanism 903 guiding the outdoor unit is shown. The rail-like means 903 may be formed by rails on which guide elements 904, such as wheels rolling in a rail structure, are arranged. In use, the outdoor unit 905 may be placed on a track-type mechanism and may be moved on a track of the track-type mechanism from a stowed position, which may be in a window, for example, to an external final position outside the wall 300.
In fig. 10, another exemplary mechanism for placing an outdoor unit in place is shown. In fig. 10, an articulated arm(s) mechanism with multiple pivot points is shown. In fig. 10, some support structure (here denoted 1002) such as that described above is provided on the wall 300. The hinge mechanism 1003 is provided with a central pivot 1005 and pivots at the distal end of the hinge arm 1006. The hinged arm 1006 is configured to hold an outdoor unit 1007. Thus, by rotating the outdoor unit downward at the central pivot while the outdoor unit is attached to the hinge arm(s), the outdoor unit 1007 moves from a first position at the window to a second position where the outdoor unit is mounted.
In fig. 11, yet another exemplary mechanism for placing an outdoor unit in place is shown. In fig. 11, the elevating platform mechanism is shown. In fig. 11, some support structure (here designated 1102), such as that described above, is provided on the wall 300. A lift platform mechanism 1103 is provided. The platform mechanism 1103 may include several guide wheels 1104 configured to support and convey the outdoor unit 1106 in a horizontal direction until the unit reaches the descent mechanism 1105. In use, the guide wheels may be used to move the outdoor unit in a horizontal direction from the window, and the lowering mechanism may be used to lower the outdoor unit 1106 to an outdoor final position.
According to one embodiment depicted in fig. 12, a mounting device 104 may be provided, which is designed as a rod system with a clamping device. Fig. 12 shows the rod system in different isometric, side and top views. In such an embodiment, the support structure may comprise a bar having a length longer than the width of the window frame in which the mounting device is to be installed. This rod is advantageously able to withstand the total weight of the outdoor unit to be used in the installation. The bar may have different structural elements (support points) which rest against the inner surface of the jamb of the sash, but may also rest against the sill. The pole may also include a mounting mechanism to facilitate installation of the outdoor unit from inside the window through the window opening. In this structure, the fixing method may use the weight of the outdoor unit to keep it stable and integrated with the window frame. Further, a bracket including a self-tightening mechanism may be provided. The self-tightening mechanism can work under different working principles, such as a screw system, a link system, a lever system, etc.
In fig. 12, a mounting device 104 is shown comprising a set of telescopic rods 701 arranged to enter into a fixed rod 702. The length of the rods 701, 702 may be selected according to the size of the window in which the outdoor unit is to be installed. In fig. 12, a support rod 703 is shown. The support rods 703 are used to provide a hinge mechanism that serves as a seating mechanism. Further, some support elements 704 may be used to improve the stability of the support structure, but also limit the relative displacement of the telescopic rod(s) 701. A support member 704 may be provided to interconnect the support rod with the telescoping rod 701. Also, the displacement of the support element 704 may be locked using the fixing element 705.
Further, in fig. 12, a gripping element 706 as part of the gripping structure may be provided together with a stop 707. The clamping element 706 and/or the stop 707 may be used to clamp the support structure to the window frame to provide a more secure mounting. Furthermore, a locking element 708 may be provided to keep the rod system locked on the window frame. Also, when mounting the rod system in a window, an adjusting bolt 709 may be used to provide support in the vertical plane. The adjustment bolt 709 may be located above the window sill and may be adjusted to adjust the position of the mechanism in the horizontal plane. A displacement rod 710 arranged to interconnect the support rods 703 may be used to provide support and rigidity to the system and to facilitate parallel movement of the gripping elements 706. Further, the pivot 711 may be used as part of a hinge mechanism. Using the pivot 711, the rotating arm 712 may provide translational and rotational movement to position the outdoor unit from an initial position in the window to an outdoor position. Further, a link member 713 hooking the outdoor unit to the mounting apparatus may be provided. The linking element may be disposed on a top portion of the rotating arm 712.
The mounting device as described herein may be advantageously attached to the outdoor unit of the air conditioner by using some guiding element within the outdoor unit housing.
